No to translate it properly into English you would have to do that yourself 
because your system has the details to decode the kernel oops below.
Help on that is written in /usr/src/linux/README, the part called;
IF SOMETHING GOES WRONG:  

Now lets see if i can take a guess at what you are doing, considering you 
give is no further information on what you are doing then all one can do is 
guess.

Possably you have compiled a new kernel and or a experimental kernel series, 
ie; 2.5.x, you may have upgraded some or other utillity which is uncompatable 
with your kernel version.

Or had your machine been running for a very long time,? do you have a swap 
space, how many programs were you using at the time of the crash, what 
processes were running, what was the last thing you did before the crash?

All and any info is better than the zero info you gave.

It could also be that you have a rouge program/daemon running which is doing 
things that kswapd did not like. kswapd is mentioned in the oops, however 
that does not mean kswapd caused the problem, kswapd is the daemon that died, 
looks that way to me.

Help us to help you, o BTW, if this happened with a 2.5.xx kernel then send 
your "detailed" message to the applicable "MAINTAINER" stated in the 
MAINTAINERS list in the kernel source and not here, experimental kernels 
should not be used by newbies unless they know what they are doing.

NOTE, i used the word newbie as a general term to reflect to this list of 
which you are a list-member.
